HOW DOES FOUR-WHEEL DRIVE
WORK
Using the 1-Speed Automatic Four-
Wheel Drive System
The 1-speed automatic four-wheel drive
system utilizes an electronically controlled
on-demand 1-speed transfer case. This
system monitors various vehicle sensory
inputs to provide an increased level of
performance. This system offers the driver
two-wheel drive high, four-wheel drive auto
and four-wheel drive high as available modes
of operation via the selectable drive mode
switch. When four-wheel drive auto is
selected, the system continuously varies
power to the front wheels for optimum
performance for all on-road conditions. When
four-wheel drive high is selected, the system
provides power to the front and rear wheels
for use in off-road or slippery conditions such
as deep snow, sand or mud. There is further
information on driving in unique driving
conditions. See Driving Hints (page 384).
Using the 2-Speed Automatic Four-
Wheel Drive System (If Equipped)
The 2-speed automatic four-wheel drive
system utilizes an electronically controlled
on-demand 2-speed transfer case. This
system monitors various vehicle sensory
inputs to provide an increased level of
performance. This system offers the driver
two-wheel drive high, four-wheel drive auto,
four-wheel drive high, and four-wheel drive
low as available modes of operation. When
four-wheel drive auto is selected, the system
continuously varies power to the front wheels
for optimum performance for all on-road
conditions. When either four-wheel drive high
or four-wheel drive low are selected with the
appropriate drive modes , the four-wheel
drive system provides electronically locked
power to the front and rear wheels for use
in off-road or slippery conditions such as
deep snow, sand or mud. Selecting slow
climb also provides additional gearing for
increased torque multiplication for conditions
like deep sand, snow, steep slopes, or pulling
heavy objects. See Slow Climb (page 297).
Additionally, the system is capable of
recreational flat towing by putting the
transfer case into neutral (N). See
Recreationally Towing Your Vehicle (page
397).
There is further information on driving in
unique driving conditions. See Driving Hints
(page 384).
FOUR-WHEEL DRIVE
PRECAUTIONS
WARNING: Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.
